Classification Of Optical Line Terminals

Optical line terminals are an important component of fiber optic transmission systems. It is a bridge between transmission equipment and users in fiber optic access networks, and a device that converts optical signals into electrical signals. It can connect users widely distributed in multiple regions together, forming a complete fiber optic transmission network.

OLT

OLT is a type of optical line terminal, mainly responsible for bridging the transmission equipment and users in the fiber optic access network. It is a device that converts optical signals into electrical signals and is responsible for the terminal access task of the fiber optic transmission network.

ONT

ONT is a type of optical network terminal, mainly responsible for converting the last mile optical signal in PON into voice, data, and video signals, and providing interface devices for end users.

ONU

ONU is a kind of optical network terminal, which is mainly responsible for signal conversion and reception after the optical fiber interface, converting optical fiber transmission data into Ethernet data, and providing users with information access to the Internet.
